mfd: Add initial db8500 prcmu register access api
This patch adds an initial PRCMU register access API, which for now should only be used for a very limited set of registers. The idea about this API is that we split the PRCMU driver in one part that deals with interaction with the PRCMU firmware and one part that simply provide write accessors in the PRCMU register range. The latter are just a collection of registers exposed in the PRCMU register range for various purposes and not related to the PRCMU firmware. Currently we support some limited GPIO, SPI and UART settings through this API.
